I’m thinking I may have bad LED board. Not matter which test I run, the LEDs after the 5th one on board 5 won’t light. Board 6 remains dark as well. The solder joints all seem fine, but I’m guessing that’s not the problem, since the first 5 LEDs on that board are fine.
From the simplified “Strandtest” sketch:
Adafruit_NeoPixel strip = Adafruit_NeoPixel(96, PIN, NEO_GRB + NEO_KHZ800);
